PROBLEM TO BE SOLVED: To provide a reflection preventing film having an appropriate color correcting function in addition to a reflection preventing function by containing a composite body of specific dyestuff. SOLUTION: A filter layer containing dyestuff and a polymer binder, a transparent carrier, and a low refractive index layer having a lower refractive index than the refractive index of the transparent carrier, are laminated in this order to form a reflection preventing film. In this case, the dyestuff contains a composite of dyestuff expressed by the formula I or II. In the formula I, Z1, Z2 are nonmetal atom group forming independently nitrogen containing heterocycle of five or six member, R1, R2 are independently alkyl group, alkenyl group, aralkyl group, or aryl group, L' is methine chain composed of odd number of methine group, and X is anion, respectively shown. Further a, b, c are respectively independently 0 or 1. In the formula II, Y1, Y2 are nonmetal atom group forming respectively independently forming the aliphatic or heterocyclic, L2 is methine chain composed of odd number of methine, and X is hydrogen atom or cation, respectively shown. |
